Agent communication and institutional reality

Fornara, Nicoletta ; Viganò, Francesco ; Colombetti, Marco

In this paper we propose to regard an Agent Communication Language (ACL) as a set of conventions to act on a fragment of institutional reality, defined in the context of an artificial institution. Within such an approach, we first reformulate a previously proposed commitment-based semantics for ACLs. In particular we show that all commonly used types of communicative acts can be defined in terms...

Algorithms and complexity results for discrete probabilistic reasoning tasks

Mauá, Denis Deratani ; Schmidhuber, Jürgen (Dir.) ; Zaffalon, Marco (Codir.) ; Polpo de Campos, Cassio (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2013 ; 2013INFO005.

Many solutions to problems in machine learning and artificial intelligence involve solving a combinatorial optimization problem over discrete variables whose functional dependence is conveniently represented by a graph. This thesis addresses three types of these combinatorial optimization problems, namely, the maximum a posteriori inference in discrete probabilistic graphical models, the...

Aligning capital with risk

Ebnöther, Silvan ; Trojani, Fabio (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2015 ; 2015ECO007.

The interaction of capital and risk is of primary interest in the corporate governance of banks as it links operational profitability and strategic risk management. Senior executives understand that their organization's monitoring system strongly affects the behaviour of managers and employees. Typical instruments used by senior executives to focus on strategy are balanced scorecards with...

Ambiguity aversion and the term structure of interest

Gagliardini, Patrick ; Porchia, Paolo ; Trojani, Fabio

In: The review of financial studies, 2009, vol. 22, no. 10, p. 4157-4188

This paper studies the term structure implications of a simple structural model in which the representative agent displays ambiguity aversion, modeled by Multiple Priors Recursive Utility. Bond excess returns reflect a premium for ambiguity, which is observationally distinct from the risk premium of affine yield curve models. The ambiguity premium can be large even in the simplest log-utility...

Un análisis gráfico de los bienes posicionales : Consumo, valoración y fallos del mercado

Vatiero, Massimiliano

In: RAE: Revista asturiana de economía, 2012, no. 46, p. 155-164

En una economía formada por dos individuos, un bien posicional es un bien tal que lo que un individuo consume en cantidad positiva debe ser consumida por el otro en la misma cantidad negativa. De este modo, los bienes posicionales constituyen el caso opuesto al de los bienes públicos. Por ejemplo, si un individuo consume más de un bien público, todos los agentes consumirán más de ese...

Analysis and new constructions of generalized barycentric coordinates in 2D

Anisimov, Dmitry ; Hormann, Kai (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2017 ; 2017INFO004.

Different coordinate systems allow to uniquely determine the position of a geometric element in space. In this dissertation, we consider a coordinate system that lets us determine the position of a two-dimensional point in the plane with respect to an arbitrary simple polygon. Coordinates of this system are called generalized barycentric coordinates in 2D and are widely used in computer...

Analysis and optimization of task granularity on the Java virtual machine

Rosà, Andrea ; Binder, Walter (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018INFO008.

Task granularity, i.e., the amount of work performed by parallel tasks, is a key performance attribute of parallel applications. On the one hand, fine-grained tasks (i.e., small tasks carrying out few computations) may introduce considerable parallelization overheads. On the other hand, coarse-grained tasks (i.e., large tasks performing substantial computations) may not fully utilize the...
